<span>The answer is : Increasing the key length of DES would protect it against brute force attacks. </span>Brute force is when the attacker tries every key knowing that one will eventually work. <span>Key length increase proportionally increases the key space, having a keyspace l</span>arge enough that it takes too much time and money to accomplish a brute force attack.
Answer: Feedback
Explanation: Feedback is the reaction obtained in the form of information from the task a person has performed or any product. It gives the review of the service that is given by the customer, user etc.The reaction that is obtained can be a negative feedback or positive feedback.
Both types of feedback is necessary because it helps in the improvement of the service. The negative reaction will helps to change/improve the service that is not liked by the customer and positive feedback tells about the services appreciated by the customer. So, Shelby is also keeping the feedbacks for the same purpose for her salon business.

Answer:
UDP Port 69
<em>Trivial file transfer protocol (TFTP) operates over UDP port 69.</em>
Explanation:
UDP port 69 uses the Datagram Protocol, a communications protocol for the Internet network layer, transport layer, and session layer. This protocol when used over PORT 69 makes possible the transmission of a datagram message from one computer to an application running in another computer. UDP is used with <em>IP (the Internet Protocol)</em> and UDP Port 69 is <em>connectionless </em>which means it does not give reliable communication; it’s up to the application that received the message on Port 69 to process any errors and verify correct delivery.
Answer:
Option d) B is 1.33 times faster than A
Given:
Clock time, 

No. of cycles per instructions, 

Solution:
Let I be the no. of instructions for the program.
CPU clock cycle,
= 2.0 I
CPU clock cycle,
= 1.0 I
Now,
CPU time for each can be calculated as:
CPU time, T = 


Thus B is faster than A
Now,


Performance of B is 1.33 times that of A
